Detailed Description
As shown in fig. 1 to 4, the present invention provides a vertical oil-water separator, comprising:
the oil tank comprises a tank body 1, wherein the top of the tank body 1 is provided with a liquid inlet 11 and an oil outlet 12, and the bottom of the tank body 1 is provided with a water outlet 13;
the separation bed 2, the separation bed 2 is set up in the tank 1;
the extrusion component 3 is arranged in the tank body 1 and positioned below the separation bed 2 in a vertically sliding manner, and a water flow channel 300 penetrating through the extrusion component 3 is arranged on the extrusion component 3;
the compressible filter layer 4 is used for adsorbing oil contained in water, and the compressible filter layer 4 is arranged between the separation bed 2 and the extrusion assembly 3;
and the hydraulic driving assembly 5 is arranged at the bottom of the tank body and is used for driving the extrusion assembly to move so as to extrude the compressible filter layer.
Specifically, in the actual use process, the oil-water mixture enters the top of the tank body 1 through the liquid inlet 11, and the mixture entering the tank body 1 flows to the lower separation bed 2. The separating bed 2 is transversely arranged in the tank body 1, after the mixture passes through the separating bed 2, the water and the oil are separated from each other under the separating action of the separating bed 2, and meanwhile, the separated oil is combined with each other to form larger oil drops. The specific gravity of oil drops is lighter than that of water, so that the oil drops can rapidly rise and form an oil storage area at the top of the tank body 1, wherein the structure configuration of the conventional oil-water separator can be referred to in the oil-water separation mode of the separation bed 2, and is not limited or described herein. In addition, for the compressible filter layer 4, a sponge body such as an oil absorption sponge, or a hydrophobic oleophilic type Polydimethylsiloxane (PDMS) elastic framework material with a three-dimensional porous structure, etc. may be adopted for preparation, which is not limited and described herein.
The water separated by the separation bed 2 also contains a small amount of oil, the water continues to flow downwards to the compressible filter layer 4, the water is filtered by the compressible filter layer 4, so that the oil contained in the water is adsorbed by the compressible filter layer 4, and finally, the water flows to the bottom of the tank body 1 through the water flow channel 300 on the extrusion assembly 3 and is discharged to the outside of the tank body 1 from the water discharge port 13.
As the usage time increases, the amount of oil absorbed in the compressible filter layer 4 increases, and the oil absorption capacity of the compressible filter layer 4 decreases gradually. At this time, the pressing unit 3 is driven by the hydraulic driving unit 5 to press the compressible filter layer 4. As shown in fig. 3, the hydraulic drive assembly 5 will drive the squeezing assembly 3 to move upwards by means of hydraulic pressure, so that the compressible filter layer 4 is sandwiched between the squeezing assembly 3 and the separation bed 2, and the oil in the compressible filter layer 4 is squeezed out. Since there is still a large amount of oil-water mixture above the squeeze assembly 3, the squeezed oil will float to the top of the tank 1. And after hydraulic drive subassembly 5 resets, extrusion subassembly 3 will descend gradually thereupon, can expand gradually after compressible formula filter layer 4 releases pressure, and in the in-process of inflation, compressible formula filter layer 4 will adsorb a large amount of water and a small amount of oil, and then makes compressible formula filter layer 4 resume filtration ability again.
Wherein, in order to improve the effect of oil-water separation, the tank body 1 is provided with a plurality of layers of separation beds 2 from top to bottom, taking the three layers arranged in the attached figure 1 as an example. After the oil-water mixture is subjected to three-layer separation treatment, oil and water can be effectively separated, so that the treatment efficiency is improved. Meanwhile, a water distributor 111 may be further disposed on the liquid inlet 11, and the water distributor 111 is transversely disposed above the separation bed 2 to uniformly distribute the oil-water mixture to the separation bed 2 below through the water distributor 131, thereby improving the oil-water separation efficiency.
In order to facilitate the control of the discharge of the oil accumulated on the top of the tank 1, a mounting port 14 may be further provided on the top of the tank 1, and a level meter (not shown) may be provided in the mounting port, and specifically, the level meter may detect the amount of the oil accumulated on the top of the tank 1, and when the amount of the oil accumulated reaches a discharge standard, the oil discharge port 12 may be opened to discharge the oil to the outside. And the oil drain 12 is located above the liquid inlet 11 to facilitate the output of oil and reduce interference associated with the incoming mixture.

Specifically, in the actual use process, when the compressible filter layer needs to be subjected to extrusion treatment, high-pressure water enters the hydraulic cavity through the water inlet pipe 15. Under the action of hydraulic pressure, the piston 52 moves upwards to drive the extrusion assembly 3 to move upwards, so that the extrusion treatment on the compressible filter layer is realized. Since the upper portion of the cylinder 51 is provided with the relief hole 511, when the sealing ring 53 passes the relief hole 511 during the up-and-down movement of the piston 52, the hydraulic chamber is communicated with the relief hole 511
The pressure of the hydraulic cavity is released due to the action of the pressure release hole 511, and at this time, the piston 52 does not continue to go up to a certain extent, so as to control the compression amount of the compressible filter layer.
Preferably, in the actual use process, after the pressure in the hydraulic cavity is relieved through the pressure relief hole 511, under the gravity of the extrusion assembly 3 and the expansion force of the compressible filter layer 4, the extrusion assembly 3 drives the piston 52 to move downwards and the sealing ring 53 moves downwards to cut off the communication between the pressure relief hole 511 and the hydraulic cavity, and at this time, the compressible filter layer 4 generates a certain amount of expansion. At the same time, the water inlet pipe 15 continues to supply water, so that the pressure in the hydraulic cavity gradually rises again and drives the piston 52 up and down again, and then the piston 52 is used for driving the extrusion assembly 3 to extrude the compressible filter layer 4. The operation is repeated for a plurality of times, so that the hydraulic driving assembly 5 and the extrusion assembly 3 are matched to alternately extrude and release the compressible filter layer 4, and then the oil extrusion recovery operation of the compressible filter layer 4 can be more fully and efficiently carried out.

The supporting frame 33 may be a grid structure to effectively reduce the weight while satisfying the structural strength requirement. The extrusion assembly 3 further comprises a connecting water pipe 34, and the connecting water pipe 34 is connected between the corresponding first water outlet and the corresponding second water outlet. Specifically, the water above is delivered to the lower space of the tank 1 via the connection water pipe 34. In order to prevent a large amount of water from flowing into the upper part of the squeezing assembly 3 through the connection water pipe 34, a check valve may be disposed on the connection water pipe 34 to realize one-way flow of water in the connection water pipe 34, because water leaking from the pressure relief hole 511 will enter the lower part of the squeezing assembly 3 during the squeezing process of the compressible filter layer 4.
Further, in order to improve the sealing strength between the compression assembly 3 and the inner wall of the can body 1, the outer edges of the first support plate 31 and/or the second support plate 32 are provided with a sealing ring (not shown) for sealing a connection region formed between the compression assembly 3 and the inner wall of the can body 1; and/or, a sealing gasket (not shown) for sealing a connection region formed between the compressing assembly 3 and the inner wall of the can body 1 is provided between the first supporting plate 31 and the second supporting plate 32.
